Abstract (en)
[origin: WO2020170092A1] The present invention relates a novel process for preparing a compound of Formula I, wherein, R1, R2, R3a, R3b, R3c, R4, R5, R6, R7 and Z are as defined in the description. The process comprises a novel and inventive step of converting a dione of Formula II into an isatoic anhydride of Formula V in a single step, wherein, R2 is F, Cl, Br or I; R1, R3a, R3b, R3c, R4, R5, R6, R7 and Z are as defined in the description.
